Angolese brilvogel Zosterops kasaicus

A small, sharp-billed warbler-like bird that is saturated with yellow. Note the yellow underparts, olive-yellow back, and bold white spectacles around the eyes. Found in forest, savanna, scrub, gardens, moist woodland, and plantations, usually in hyperactive flocks that can contain many individuals. Often joins mixed flocks with other small birds. Most common call is a high-pitched rising rattle. Song is a quiet, chatty sequence of “chew” notes. Similar to Pale White-eye, but usually separated by range; shows more yellow above the bill, is more richly-colored overall, and prefers moister habitats. Also similar to Southern Yellow White-eye, and separation and degree of range overlap is poorly understood.
